I'm looking for a 13.875 MHz crystal for my teletext project. I've tried
maplin, farnell and RS and none of them seem to stock it. I _know_ they are
available somewhere because I've seen them in the past in some old Dragon/
Tandy TRS 80 computers for video generation -I think they are a multiple of
the colour burst frequency or something- but I dont really want to dismantle
some antiques just to get my part. I've looked at digikey and they have
something close which I assume is the NTSC equivalent of the PAL 13.875, but
its not close enough. Does anyone know of another UK supplier that might
stock this part?
